Drop the top-frequency OPPs from both the LITTLE and big CPU clusters on RK3576, as neither the opensource TF-A [1] nor the recent (after v1.08) binary BL31 images provided by Rockchip expose those.
This fixes the problem [2] when the cpufreq governor tries to jump directly to the highest-frequency OPP, which results in a failed SCMI call leaving the system stuck at the previous OPP before the attempted change.
